OpenRC Tractor - Backblade
thingiverse
I took the universal hook that was in OpenRC Tractor Rake software and tinkered a simple back blade type attachment to the 3-point hitch. We used to use these to scrape the barn or level driveways. I used the cardboard from a cereal box and striped the bottom side with a magic marker. Sandwiched between two plastic guides it made for a reasonable plow point. I did include a template that can printed to use to trace around on your cardboard. Simple .. but it worked.
